Importing models into LightWave

Comments apply to version 5.x
The two easy import formats for LightWave are DXF and OBJ files.
Unfortunately there seem to be rather restrictive limits on the
size of objects, in particular there appears to be a limit of 65535
(2 byte vertex index maybe) to objects. When importing OBJ formats
a large number of vertices seem to be read OK but the vertex indices
in the face list are added modulo 65536 (It would save a lot of grief
if sensible error messages were given in these circumstances!). When
importing large DXF models the importing generally fails at some point
after 65536 facets.
The solution is to split the model up into a number of separate DXF
or OBJ files, import each one and save the object. A tedious process
and exactly the sort of thing one expects computer software to do
for us.

Example DXF file

The following is an example DXF file illustrating how
faces can be imported into LightWave. The red comments should not be included.
